SPECIFICATION forming part of Letters Patent No. 845,695, dated July 1886.

Application filed March 13, ISEGQ Serial No. 195,118. (No model.)

To aZZ whom it may concern:

Be it known that 1, Isaac D. Hnnennn, of Lansdale, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Thrashing- Machines; and I do hereby declare the following to be a full, clear, and exact description grain and chaff from the straw with a separator or strawcarrier of minimum length and without liability of there being any grainthrown out over the ends of said separator or straw-carrier by the action of the thrashingcylinder.

I will first describethe invention at length, and will then point out the particular features of novelty in the claims at the close of this specification.

In the accompanying drawings, Figure 1 is a longitudinal section of a portion of the thrashingmachine, showing the application of my improvements. Fig. 2 isa front view of the straw-feeder and grain-arrestcr detached; Fig. 3, an end view of the same; Fig. 4, a view of a modification of the means for maintaining the blades of the straw-feeder and grain-arrester at all times in perpendicular position; Fig. 5 is a detail view showing the manner of attaching the blades to their respective shafts.

Similar letters of reference in the several figures denote the sameparts.

The letter A represents the th rashing-cylinder, and B the concave with which it co-operates.

Ois the separator or straw-carrier, which may be of any suitable construction, though I prefer it to consist of perforated sheet-iron secured to a frame which is mounted on swinging supports, that enable it to be given a vibratory or shaking motion.

In rear of the thrashing-cylinder is arranged an inclined deflecting-board, D, and in rear of this board is arranged what I term my strawfeeder and grain-arrester, the office of which is to act upon the straw as it comes from the thrashirig-cylinder, part it, so as to permit the thrashed grain to pass through, and feed it positively forward over the separator orstrawcarrier, and at the same time operate as an arrester or barrier to flying grain, thatmight otherwise be projected out over the end of said separator. This straw-feeder and grain; arrester in perhaps the simplest form consists of a shaft, 19, mounted in suitable bearings in the sides of the machine and having secured to it disks or heads F F, as shown clearly in Fig. 2. Journaled in these two disks or heads is a series of shafts, G, each of which bears a blade, 11, preferably of metal. The connection between the blade and the shaft is pref erably secured by slotting the shaft longitudinally and inserting the body of the blade in said slot and securing it by bolts or rivets 9, passed transversely through it and through the shaft, as shown in Figs. 1 and 2. The connection between the shaft and blade is further strengthened and made more secure by cutting away a portion of one end of the blade and causing it to interlock with the shaft at the point where the slot of the latter terminates, as shown in Fig. 5.

The number of shafts and blades may be varied as desired; but I prefer to employ six of them, as shown.

To one end of each ofthe shafts Gis secured a crank, l, whose wrist is connected to a circular rim, K, which is mounted on a support, L, so as to revolve on an axis eccentric to that of the main supporting-shaft E. This support L consists of a plate of metal or other material of substantially the diameter of the circular rim K, secured to the casing, and preferably provided on its upper side with a small antifriction wheel, Z, on which the rim normally rests, and, being kept to one side of the axis of rotation of the shaft and connected to each of the blades, the rim will be revolved with the heads F F, as shown. The effect of this arrangement of partsis to cause the blades H to ceives motion from any suitable rotating part of the thrasher, said pulley being preferably a cone-pulley, in order that different rates of speed may be given accordingly as different kinds of grain thrashed may require.

\Vhen the machine isin operation, the shaft E and parts carried thereby are rotated in the direction indicated by the arrow, Fig. 1that is to say, in a direction contrary to that in which the thrashing-eylinder is rotated-and the blades II descend in succession upon the stream of straw discharged from the thraslr ing-cylinder, sweep forward toward the outer end of the separator or straw-carrier, and impart to the straw a positive forward feed, at the same time presenting a barrier which arrests any flying grain and preventsit from being thrown over the tail of the straw-carrier. The lower ends of the blades H are preferably made with fingers or teeth, as shown, for the purpose, iirst, of separating the straw as they descend upon it, and allowing the grain to fall through; secondly, ofenabli ng the said blades to secure a more positive hold upon the straw and withdraw it quickly from the thrashingcylinder and prevent it from becoming clogged and wound upon the laiter, as might otherwise be the ease.

I do not desire to confine myself to the particular device shown for keeping the blades H in perpendicular position during their revolutions around the axis of the shaft E, as there are many other ways of accomplishing the same result. For instance, each of the shafts G may, as shown in Fig. 4, be provided on its end with a pinion, O, in mesh with one ofa series of idle-pinions, I, that are also in mesh with a stationary pinion, Q. I prefer, however, to employ the construction shown in Figs. 1 and 3.

In rear of the straw-fceding and grain-arresting device is arranged a spring-actuated apron, It, normally pressed toward the thrashing-cylinder by a light spring, but adapted to be pressed backward to the position shown by dotted lines against the spring when the straw is thrown upon it. This will prevent the flying grain from passing through, but will permit the passage of the straw, and it can be used with advantage with a stationary apron. As a further caution against the escape of flying grain, I attach to a rearwardlyinclined board, S, an apron, T, of leather or other flexible material. All these contrivances tend to effect the thorough separation of the grain from the ehaffand straw in a rapid and expeditious manner, and render it feasible to employ a separator or straw-carrier of minimum length. N ot only do the revolving blades, by their action upon the straw, operate to keep the thrashing-cylinder clear, but they also prevent the straw from being cut or chopped up or otherwise injured.

I claim as my invention 1. In athrashing-machine, the combination, with the thrashing-cylinder and the separator, of the combined straw-feeder and grain-arrester, consisting, essentially, of series of rotating blades, and means whereby they are held in substantially-perpendicular position during their rotation, substantially as described.

2. In a thrashing-machine, the combination, with the thrashing-cylinder and the separator or straw-carrier, of aseries of blades arranged to descend suceessivelyinto the straw and then move rearward and upward, and means whereby they are maintained in substantially-me tical position during their movements, sub stantially as described.

8. In athrashing-maehine, the combi nation, with the separator or straw-carrier, of the retating shaft and heads or disks mounted there on, the series of shafts journaled in said heads and carrying the blades, with mechanism, sub stantially as described, for maintaining the blades in a substantially-vertieal position during the rotation of the heads, substantially as described.

4. In athrashing-maehine, the combination, with the thrashing-cylinder and the separator or straw-carrier, of the series of straw-feeding and grain-arresting blades having the fingers or teeth on their lower edges arranged to descend successively into the straw and then move rearward and upward,and means where by they are maintained in substantially-vertical position during their movement, as set forth.

5. In a thlashing-machine, the combination, with the separator and the combined st awfeeder and grain-arrester,constructed substantially as described, of the co-operating pivoted spring-pressed apron, substantially as described.

0. In athrashing-mzpchiue, the combination, with the separator and the combined straw- .feeder and grain-arrester,constructed substantially as described, of the cooperating pivoted springpressed apron and the apron of flexible material, substantially as described.
